Today, with the significant advances in the technology of making superconducting materials, the use of these materials has increased greatly, which can be mentioned in medical engineering, power, and electronics. The use of superconducting wires in electric machines, including transformers, synchronous generators, and propulsion motors, has made great progress in recent years. One of the most important challenges for superconducting wires is the high price of these wires, which has been solved to a good extent with the developments in this field, such as Iron-based wires. In this thesis, a 36.5 MW 120 rpm superconducting synchronous motor with field windings consisting of iron-based superconducting wires has been designed and studied. Iron-based superconducting wire has been used in the field, which increases the potential of competition in the field of superconducting machines due to its good mechanical properties, high critical values, and reasonable price. In this thesis, the design method of superconducting synchronous motor and how to predict the magnetic fields in different parts of the motor along with multiphysics analysis has been done. The design of an electric motor has different dimensions, which cannot be considered complete or applicable only after receiving confirmation from the electromagnetic analysis. Therefore, multiphysics analysis is necessary for the design of an electric machine. The superconducting motor designed in this thesis increases the importance of performing multiphysics analysis for this motor due to the existence of some differences in the structure and materials used in the motor. The use of copper coils in the armature part has created a large number of heat sources in this part of the electric motor, which must be able to withstand this heat in the motor structure and the new materials used in the motor. The thermal analysis of the designed synchronous motor in this study is carried out and the results are presented. The force applied on the armature teeth also needed to be checked due to the use of new material therefore, the Von Mises criterion was checked in this part of the motor. The 36.5 MW superconducting synchronous motors made with high temperature superconducting materials and similar motors designed by low temperature superconductors are compared with the proposed motor and finally, an optimal superconducting synchronous motor is designed for use in the ship propulsion system which has 99% efficiency. The eva‎luation results of this motor show an acceptable model for it.
